如何使用GLES 3从android屏幕读取像素数据

Question

i am using GLES 3 to create 3D textures and render data in surface view. Is it possible to read this data from the screen/texture some how.

Answer 1

You can read what you've rendered with glReadPixels() , but that tends to be slow.

Depending on what you're trying to do, you may get better results by rendering to an FBO.

You can find some example code in Grafika ; see for example EglSurfaceBase#saveFrame() .
